The most useful email segments group contacts by engagement (engaged, less engaged, unengaged) and purchase history (never bought, first-time buyers, repeat buyers, lapsed regulars). Subscription and loyalty segments add more if you sell those.
Sending every email to everyone is the fastest way to teach customers to ignore you. Segmentation fixes that: you group people by what they bought, how they shop and how they respond, and send each group the message it actually wants. Fewer people get messages that don't fit, fewer unsubscribe, and the people who do get a message are more likely to act on it.
Below are 14 segments worth building, with the exact rules, what to send each one, and the mistakes to avoid. They work for email and texts alike.
What is an email segment?
A segment is a group of contacts who match conditions you set, such as "placed two or more orders" or "clicked an email in the last 30 days." Good segments are rules, not fixed lists: people move in and out on their own as they buy, click and change their preferences, so a campaign always goes to whoever matches on the day it sends.
Engagement segments
Start here. Sending mostly to people who engage protects your sender reputation, which decides whether any of your email reaches the inbox.
- 1. Engaged in the last 90 days: Rule: clicked an email in the last 90 days OR placed an order in the last 90 days OR joined in the last 30 days. Send: your regular campaigns. This is your default audience.
- 2. Less engaged: Rule: no clicks or orders in 90 days, but some activity in the last 180 days. Send: your biggest campaigns only, perhaps one or two a month.
- 3. Unengaged: Rule: no clicks or orders in 180 days or more. Send: a re-permission message, then stop (see how to clean your email list).
Why clicks and orders rather than opens? Apple's Mail Privacy Protection downloads email content in the background by default (checked October 19, 2026), so an "open" doesn't prove anyone read the email. Pick windows that fit how often your customers buy; 90 and 180 days are starting points, not rules.
Purchase segments
- 4. Subscribers who never bought: Rule: number of orders is 0, joined more than 14 days ago. Send: best-sellers, reviews and answers to the usual first-order doubts.
- 5. First-time buyers: Rule: number of orders is exactly 1, last order in the last 60 days. Send: how to use what they bought, then what goes with it.
- 6. Repeat buyers: Rule: number of orders is at least 2. Send: new products first and thanks for coming back.
- 7. High spenders: Rule: amount spent is at least a figure that marks your top customers (look at your own order data). Send: early access and the occasional thank-you without a discount.
- 8. Lapsed regulars: Rule: number of orders is at least 3 AND last order placed more than 90 days ago. Send: what's new since they last bought, and a reason to come back.
- 9. Bought a product or category: Rule: orders containing a product, variant or collection. Send: refills, accessories, care tips or the next step in the range.
- 10. Discount shoppers: Rule: used a discount code on most orders. Send: bundles and value messages, and consider leaving them out of some full-price launches.
RFM (recency, frequency and monetary value) is a classic way to combine segments 5 to 8: score customers on how recently they bought, how often and how much, then group them. You can get most of the benefit with plain rules like the ones above: last order date, number of orders and amount spent.
Behavior segments
- 11. Browsed but didn't buy: Rule: viewed a product in the last 7 days AND placed no order in the last 7 days. Send: the products they looked at, or best-sellers in that category. Usually handled by a browse abandonment flow.
- 12. Text subscribers who click: Rule: text consent is subscribed AND clicked a text link in the last 30 days. Send: your most important texts first.
Subscription and loyalty segments
- 13. Subscribers billing soon: Rule: has an active subscription AND next billing date within the next 3 days. Send: a reminder to swap, skip or add something to the order.
- 14. Loyalty members near a reward: Rule: points balance at least your lowest reward threshold, or reached a new tier in the last 7 days. Send: what they can redeem or their new perks.

| Browsed | Viewed product, no order, 7 days | Browse abandonment |
| Engaged texters | Text consent and a click in 30 days | Key texts first |
| Billing soon | Active subscription, bills in 3 days | Swap or skip reminder |
| Near a reward | Points over threshold or new tier | Redeem, new perks |
How do segments work with flows?
Segments decide who gets a campaign; flows react to what someone just did. They work best together. Use segments as filters inside flows (for example, send a different welcome email to someone who has already bought), and use flows to move people between segments: a win-back flow targets your lapsed regulars, and an after-purchase flow turns first-time buyers into repeat buyers. See the flows every Shopify store should run.
Mistakes to avoid
- Too many tiny segments: A segment of 40 people isn't worth its own email. Start with five or six and add more when you have something different to say.
- Overlapping sends: One customer can be in several segments. Use a frequency limit so overlapping campaigns don't all reach them on the same day.
- Fixed lists that go stale: An exported list of "VIPs" from January is wrong by March. Use rules that update themselves.
- Ignoring consent: A segment never overrides consent. Texts go only to people who agreed to texts.
Build these segments in SmartyTap
SmartyTap segments are rules that update as customers change, and because subscriptions, loyalty and messaging share one customer record in Chargezen, one segment can check all three. Conditions include:
- Orders and revenue: Number of orders, subscription orders, amount spent, last order placed, products and variants ordered, discount codes used and order source.
- Subscriptions: Active subscription, status (active, paused, cancelled, expired, failed), billing and delivery interval and next billing date.
- Loyalty: Points balance, current tier and when they entered it, and last loyalty activity.
- Engagement and consent: Emails delivered, opened, clicked and bounced; texts sent and received; text link clicks; email and text consent.
- Profile and site activity: Location, time zone, language, birthday, and storefront activity such as viewing a product or adding to cart.
A live preview shows how many contacts match before you save. SmartyTap doesn't score customers with RFM or predict lifetime value; build similar groups from orders, spend and last order date. Step-by-step setup is in Segments, and audience data shows the customer record behind them.

Frequently asked questions
What are the most important email segments?
Start with engagement (engaged, less engaged and unengaged), then purchase history (never bought, first-time buyers, repeat buyers and lapsed customers). Those seven cover most of what a store needs and protect your sender reputation.
How many segments should I have?
As many as you have different messages for. Most stores start with five or six and add more when a group needs something genuinely different, such as subscribers or loyalty members.
What is the difference between a segment and a list?
A list holds the people you put in it. A segment is a rule, so people join and leave it on their own as their orders, clicks and consent change.
Do I need RFM to segment my customers?
No. RFM is one method of combining recency, frequency and spend. Plain rules on last order date, number of orders and amount spent give you most of the same groups.
